The combo says it includes 3 tunes. I'm assuming they are for 87, 91, & 93 octane.

Will these tunes change my auto tranny's program or will I have to do that myself?

Do I still have to take the car to a shop for custom tuning?

They will be 87-89-93 and yes they will wake your automatic up big time.
Mine will chirp 2nd and third gears.
You can dyno your car and fine tune it ,but the tunes you get will be pretty close.
Have Fun!!!!!

Actually, the octane tunes will be whatever you ask for, I got mine from Brenspeed @ 87, 89, and 92, which is what gas is around here. Just tell em what you want when you order. The tunes include tuning the auto trans, and you will see a HUGE difference. Anyone who has an auto must get a tune, it's a totally different car after, you will be amazed. I have only used the 89 tune (with 92 gas) and chirp second and third, just make sure the road or your tires are not wet! It also goes a little sideways on the 1st to 2nd shift @ WOT. Warren..

Great. I'll have to throw some of my junk on ebay and order the combo.
